A flap configuration has a flap for closing a receptacle and a closing slide guided displaceably parallel to the flap plane in the closing slide guide. The compression is adjusted to cause the load plate to provide a target load when installed in the ASIC assembly. The soluble fiber may in particular be derived from plantains or bananas. The optical head assembly is moved by the calculated distance toward the burst cutting area. At least one of the first and second lenses has a diffractive optical surface, the diffractive optical surface having twenty or less orbicular gratings in a range to pass an effective light ray. For two signal paths, a faster signal may be delayed by a digital processor or a slower signal may be transmitted early so that signals in the two signal paths arrive at a specified circuit node in synchronization.
